I suggest one medium size whitefish fillet per person
Debone any large bones
Make an aluminum foil square boat with sides folded up and put the whitefish  fillet, skin side down
Spread a thin coating of mayonnaise on top
Sprinkle fine chopped garlic over fish
Sprinkle, dill, celery salt and paprika on top
Put on Grill for 12-15 minutes approx. 350 degrees, don’t flip.
You can also do this with Salmon and other light fishes.
